78mm is stock, FAST makes a TB that will max out to the stock intake neck. Some have had them enlarged to 90MM but honest gains I have never seen.

Do not touch the MAF.

Look at a hand ported stock TB.

First mod should be a Air LID. Do a search.

Stock 99 TA WS6.
Definetly i recommend a shifter like pro 5.0 and a skip shift delete for manual, it would be a relief, Save for an ls6 intake manifold, p&p tb, then headers and exhaust, the car needs to breath like a human after that upgrade the valvetrain and a tune, etc.

Then change your sig. It is not FULLY stock....

Anyways, save for the LS6, headers, a good catted Y and a cat back. At that point you WILL need a bolt on tune since you should be maxing out the current one and pulling timing.

Depending on what your buy your at least over 2k in parts so save the MAF and TB money for something that actually works.
